PURPOSE:To simplify operation control and prevent waste of power by starting/ stopping an electrically-driven motor on the basis of a control position of a manual handle. CONSTITUTION:Neighboring switches 7, 8, provided on manual handles 5a, 6a for each of direction selector valves 5, 6, are assembled into the control circuit of an electrically-driven motor 1. Due to this structure, said motor 1 automatically starts or stops through only operation of the manual handles 5a, 6a, therefore, operation control of the captioned device can be simply performed. Further, in case the manual handles 5a, 6a are in neutral positions and supply of pressurized oil is not required, since the electrically-driven motor 1 automatically stops, waste of power for driving said motor 1 can be prevented. |
